One of the philosophies that believes in past lives reincarnation and other births for the soul is the Hindu philosophy. The Hindu philosophy also believes in athma (soul) and karma (deeds). Hindu religious scriptures say that the soul never dies but merely changes body or form, much as one might shed old clothes for new.

This differs greatly from Christianity, which has as its focus Christ's resurrection. The Hindus state that the soul can take any form, whether man, woman or animal. The deeds one does in one's present life, or karma, will dictate what happens to someone in the next life.

There are several Hindu scriptures that speak very much about past lives reincarnation. Notable among these is the Bhrigu Sanhita, which apparently had a complete accounting of both past and future births for all living souls. Unfortunately, this scripture has been lost over time.

Most compellingly, Dr. Ian Stevenson has collected modern rebirth data. Although scientists still frown on the claims of rebirth, such that it cannot be said that modern science respects so-called 'scientific information' on reincarnation theory, Stevenson's work is the most well-documented and famous; not least, that was because Dr. Stevenson had a degree in medicine and was a psychiatrist.

Unlike today's past life regression therapists, though, Dr. Stevenson didn't put his patients into trance or hypnotize them. Instead, he interviewed children who had spontaneous recollections of the incidents they experienced in their past lives.

Among the most well-known and puzzling cases was that of a child, a young boy, six years old, from a tiny village in Punjab. This child claimed that he had been Satnam Singh, a man from a village that the boy named as Chakkchela; the boy claimed to have lived there as Satnam Singh, even though he actually had not been there himself. Additionally, the boy could describe Chakkchela in minute detail.

The family tried to stop the boy from discussing this, but the boy was not dissuaded and continued. He was even able to reveal the name of the man's father. He claimed that as Satnam, he had died as a result of a motorcycle accident he'd been in as he rode home from school. Closer investigation found thatSatnam had indeed died in this manner. The boy was also able to reveal personal information about the family, but the 'clincher' was that when the child's and the man's handwriting samples were compared, they were identical.

Stevenson also interviewed a young girl named Swarnalata, another of his famous cases. This young girl was just three years old, but she remembered her past life as a young woman named Biya Pathak. The little girl could describe the house that she lived in, and even took her father there one day when they were coming back from the railway station in their town. She further said that she and her father could get a better cup of tea in Biya Pathak's house than they could on the road. Again, the final proof turned out to be when the child recognized the young woman's brother, and addressed him by a pet name the young woman had had for him, among a group of nine people.

Stevenson lists dozens of these cases in his data, and also states that in some cases, when there has been a physical trauma in the last life, it can manifest in the form of a birthmark in the next life. A man from Thailand seemed to illustrate this; he recollected that he was his own deceased maternal uncle, reincarnated. And indeed, this man had a scar on his head that was located in the exact same place as a knife wound his uncle had died from.

Another young boy claimed to remember a past life as a man named MahaRam. This man had been killed by close contact gunfire to the chest, and the boy had several birthmarks on his chest that looked like gunshot wound scars.

Dr. Brian Weiss is considered to be the father of modern past life regression, and he and several other eminent authorities in the field of psychiatry and psychology consider that the concept of rebirth is in fact a plausible one. Nonetheless, science itself remains very skeptical about it. It's also worth noting here, however, that when people do undergo past life regression therapy, they often suddenly dispense with lifelong fears and phobias.
